What is opuntia stricta?

Opuntia stricta, commonly known as the erect prickly pear or the erect opuntia, is a cactus species native to Central and South America, the Caribbean, and Florida. It has been introduced to many other parts of the world as an ornamental plant and has become an invasive species in some of these areas.

Opuntia stricta has flat, rounded, bright green pads that are covered with spines and small bristles. The pads are usually 10-20 centimeters long and 6-10 centimeters wide. The flowers are yellow or orange and appear from May to June. The fruits are edible and are used to make jams, jellies, and drinks in some cultures.

Opuntia stricta is a hardy plant that can tolerate drought and poor soil conditions. It is also resistant to pests and diseases. However, its ability to quickly spread and form dense stands can displace native vegetation, reduce biodiversity, and alter ecosystems. Control measures for this invasive species include mechanical removal, herbicide application, and biological control with insects and pathogens that target the plant.
